Well $K_{sp}$ $K_"sp"$ is unknown..........

Explanation:

I think you refer to the zinc ion in water, which we should represent as ${[Z n {(O H_{2})}_{6}]}_{6}^{2 +}$ $[Zn(OH_2)_6]^(2+)$ . Salts such as $Z n C l_{2}$ $ZnCl_2$ are mighty soluble in water (you'll have to dig for the details), but if we represent its solubility as $S$ $S$ ,

then according to the solubility equation:

$Z n C l_{2} (s) + excess H_{2} O ⇌ Z n^{2 +} + 2 C l^{-}$ $ZnCl_2(s) + "excess"H_2OrightleftharpoonsZn^(2+)+2Cl^(-)$

And so $K_{sp} = [Z n^{2 +}] {[C l^{-}]}^{2}$ $K_"sp"=[Zn^(2+)][Cl^-]^2$

And reasonably, we can equate the solubility of the salt, $S$ $S$ , with $[Z n^{2 +}]$ $[Zn^(2+)]$ . Do you agree?

And so, finally, we write, $K_{sp} = S \times {(2 S)}^{2} = 4 S^{3}$ $K_"sp"=Sxx(2S)^2=4S^3$ .

$K_{f} (Z n^{2 +} (a q))$ $K_"f"(Zn^(2+)(aq))$ is a trickier proposition.
